基于SIFT的数字博物馆图像展品校正及保护算法

SIFT-based Image Exhibits Correction and Protection Algorithms for Digital Museums

介绍了能够实现展品版权保护的数字水印技术,运用SIFT(Scale Invariant Feature Transform)技术对博物馆数字图像展品的几何变换失真(旋转、缩放、平移)进行恢复,取得较好效果,为实现基于数字水印技术的版权保护应用研究打下了基础。

This paper presents the digital watermarking technology for exhibits copyright protection. We used the SIFT （Scale ]nvarient Feature Transform） algorithm to remove distortions of museums＇digital image exhibits caused by geometric transformations （such as rotation, zooming and translation） and produced good results, laying the foundation for researching copyright protection applications based on the digital watermarking technology.
